Thread: Stereo and reverse lights

I have a 1992 Grand Prix SE and I've been having problems with the radio/stereo however you guys wanna call it, it will work fine for a few minutes but then the display will go black and i lose control over it, i can't change the station or lower the volume.. nothing. Maybe i need a new one?
The second thing; the reverse lights won't turn on. I checked them myself and they don't look damaged and no fuses are damaged either. i put the car on reverse and they don't light up.
Help please!
